SPECIFICATION forming part Of Letters Patent No. 660,371, dated October 23, 1900. Application filed February 12, 1900- Serial No. 5,006. (No model.)

To aZZ whom, it may concern.-

Be it known that I, KATE J. FOLEY, a citizen of the United States, residing at Berryessa, in the county of Santa Clara and State of California, have invented certain new anduseful Improvements in Heaters, of which the following is a specification.

My invention relates to an improved heater which is especially adapted for large rooms, such as country school houses, assemblyrooms, and the like.

In country schools, where the pupils are assembled in one large room heated by a stove, great difficulty has been experienced in maintaining the room at a suitable temperature and at the same time providing proper ventilation. Generally the windows are slightly opened. Indeed, with the ordinary stove this is absolutely necessary to-insure ventilation;

but the effect of this is to chill the pupils near the windows, while others near the stove are uncomfortably warm. A heating-furnace of the ordinary construction is out of the question in such cases onaccount of the expense of installation and difficulty of operation. Moreover, its heating capacity is greater than necessary for the purpose.

The object of my invention is to provide a heating device which may be applied to the ordinary stove in a school-house'with little expense and which requires no more care and skill in attendance than the ordinary stove.

In the accompanying drawings, Figure 1 is a plan, view of a room provided with my improved heater. Fig 2 is an end View of the heater. Fig. 3 is a cross-section thereof, and Fig. l is a vertical longitudinal section.

1 represents the floor of a room, and 2 a stove for heating the same, which in the present case is shown as specially adapted for burning Wood and having its feed-door 3 at one end. Said stove stands up from the floor on legs 4. In said floor below said stove, are set two registers 5, through which air is introduced by means of pipes 6 underneath the building, which registers may be wholly or partly closed by means of the rods 9. A casing 10 is secured on the floor around the stove. The front end of said casing has an aperture fitting tightly around the front end of the stove, and the other sides of the casing surround the stove at a distance therefrom, so

of registers 11 in the sides of the casing near the top. In order to apply to heating air in this manner the greatest possible proportion of the heat of the stove, a drum 13 is suitably supported on the stove, and the products of combustion are first passed into said drum 13 from the stove 2 through a pipe 14 and thence from the other end of the drum into the stovepipe 15. r

In order to heat the air thoroughly before it is discharged from the easing into the room, strips or sheets 16 of metal are secured to the internal walls of the casing and fit snugly against the stove, openings 17, however, being left alternately at the opposite ends of the casing to permit the heated air to pass in a circuitous path to the top of the casing.

18 represents ventilators through which the impure air can escape from the room.

Two airconduits 6 are provided, leading from opposite sides of the building, so that either may be used, as desired, according to the direction of the prevailing wind.

It will be seen that'by the above construction I provide an effective heating device which can be adapted by any plumber to an ordinary stove at very slight expense.

I claim In combination with the floor of a room, two registers in said floor, two air-inlet pipes conducting from opposite directions to the respective registers, a stove standing on legs on said floor above said registers, a drum extending longitudinally above said stove, a short vertical pipe connecting said drum with said stove, a stovepipe leading from said drum and a casing fitting snugly to the floor and surrounding the stove at a distance on all sides except that having the feed-door, and fitting snugly to said latter side, said casing having secured to its internal walls zigzag sheets of metal fitting snugly against the stove andhavin g openings between said sheets and casing to provide a circuitous path for the heated air, and having also discharge-registers in the upperportion of opposite sides of the casing, substantially as described.

In witness whereof I have hereunto set my hand in the presence of two subscribing witnesses.

KATE J. FOLEY.
